BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to an applicator tip for a cosmetic product, an applicator and an associated applicator assembly.

Description of the Related Art

Applicator assemblies for a cosmetic product are known, for example for a cosmetic product intended to be applied on the lips and/or the skin of a user. The applicator assemblies include a receptacle containing the cosmetic product and an applicator adapted to be fixed in a removable manner onto the receptacle.

The receptacle generally includes a body, with the body including walls delimiting a reservoir wherein the cosmetic product is contained, and a neck defining an opening through which the cosmetic product can be extracted. The applicator generally includes a cap adapted to be fixed onto the neck, a rod extending from the cap and an applicator tip fixed to a free end of the rod.

When the cap is fixed onto the neck, the rod and the applicator tip extend inside the reservoir. The applicator is immersed into the cosmetic product contained in the reservoir.

To use the applicator, the user detaches the cap from the neck and extracts the applicator from the receptacle.

The generally known applicator tips have a zone in the shape of a spatula intended to come into contact with the portion to which makeup is to be applied, in particular to load them with cosmetic product. However, the zone in the shape of a spatula usually allows only for a local application of cosmetic product, for example on a single lip at a time. The spatula also has a rigidity that is not comfortable when a pressure is exerted on the portion to which makeup is to be applied.

BRIEF SUMMARY OF THE INVENTION

The present invention aims to propose an applicator tip making it possible to apply make-up, in a single application, to an extended zone of a user, for example both lips, while still retaining comfort of use during the application of make-up. As such, the invention relates to a tip intended for the application of a cosmetic product on the lips and/or the skin of a user. The tip includes a sleeve and an application portion. The sleeve is intended to be assembled with a rod of which at least one of the distal ends is hollow. The application portion extends along a main longitudinal extension direction, referred to as the main direction, between two opposite distal ends, a first end referred to as proximal end and a second end referred to as the distal end. The sleeve extends from the proximal end of the application portion along the main direction in the direction opposite that which points to the distal end of the application portion.

According to the invention, the application portion includes a first and a second application zones, and a means of articulation intended to articulate the two application zones between them. The sleeve and the first application zone are integral, the second application zone being linked to the first application zone by the intermediary of the means of articulation. The means of articulation allows for a rocking movement of the second application zone with respect to the first application zone on either side of a plane of symmetry of the applicator tip, the plane of symmetry being defined by two axes X, Y of an orthonormed coordinate system X, Y, Z of which the direction X is confounded with the main direction. The means of articulation separates the first and second application zones by forming at least one reservoir of cosmetic product between the first and second application zones.

In other words, the applicator tip includes a means of articulation that allows one of the application zones to be mobile in relation to the other. This mobility limits the rigidity of the portion of the applicator and provides the applicator tip with flexibility. This flexibility provides a comfort of use, in particular for the application of a cosmetic product on the lips and/or the skin of a user.

The reservoir has the advantage of being used as an intermediate reservoir for the cosmetic product to be applied, which provides assurance to the user of having enough cosmetic product on the applicator tip in order to apply make-up, in a single application without having to reload the applicator tip with cosmetic product

According to different embodiments of the invention, which can be taken together or separately:

-   -   the first and second application zones are zones with which the         user applies the cosmetic product on the lips and/ or the skin,     -   the rocking movement is carried out around a direction of which         at least one of the components is confounded with the axis X,     -   the orthogonal projection of the reservoir in the plane of         symmetry X, Y has a curved shape generated by a parametric curve         in the plane of symmetry X, Y,     -   the means of articulation is a strip of material of which the         thickness measured along the axis Z of the orthonormed         coordinate system X, Y, Z is of about a millimetre,     -   the means of articulation is presented as a plurality of bridges         of material connecting the first and second application zones in         a finite number of points,     -   the application portion has, between the first and second         application zones, a hole allowing the user to see through the         application portion,     -   the application zones are smooth and/or flocked and/or carry a         material on their surface,     -   the material provides a surface condition of which the roughness         is modified with respect to that of the application zones taken         bare,     -   the sleeve, the first application zone, the second application         zone and the means of articulation are moulded together,         preferably in a single material,     -   when the sleeve is assembled to the rod, the manipulation rod of         the applicator tip, the portion in the vicinity of the proximal         end of the application portion, then confounded with the         vicinity of the hollow distal end of the manipulation rod, is a         portion on which the cosmetic product is not or is hardly         embedded after an immersion of the applicator tip in a         receptacle of cosmetic product, while the reservoir is a portion         in which the cosmetic product is embedded in a larger quantity         after a the immersion.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a first example of an applicator tip 10 for a cosmetic product according to the invention. The applicator tip 10 extends along a longitudinal extension main direction, referred to as the main direction and marked as X in the figures. The applicator tip 10 includes an application portion 20. The term “application portion” means a portion of the applicator tip that is able to retain cosmetic product when it is placed in contact with, and to then restore it. The application portion 20 extends along the main direction, between a first end, referred to as the proximal end 13 and a second end, referred to as the distal end 16, opposite the proximal end.

The application portion 20 has a section longitudinal to the extended main direction X, in particular of oval shape, and a section transversal to the main direction X marked within a circle of variable diameter along the axis X and of which the maximum diameter is d. This extended shape procures a larger application surface while still retaining a limited diameter of the application portion 20 in order to facilitate the insertion thereof into a receptacle 50 containing the cosmetic product. The term “application surface” means a surface devoid of protuberances such as the protuberances of mascara brushes that are used to apply the product. In other words, the application portion extends to a rod 40, referred to as manipulation rod, reducing the space between the application portion 20 and the manipulation rod 40. As such an accumulation of product at this level is prevented after wiping which risks running and hindering the application of the product.

On the other hand, the applicator tip 10 includes a sleeve 14. The sleeve 14 is intended to be assembled to the rod 40, here embedded in the rod 40, in order to form an applicator. The sleeve 14 extends from the proximal end 13 of the application portion 20 along the main direction in the direction opposite that which points to the distal end of the application portion. According to the invention, the application portion 20 includes:

-   -   a first and a second application zones 20 a, 20 b, and     -   a means of articulation 20 c intended to articulate the two         application zones 20 a, 20 b between them.     -   The first and second application zones 20 a, 20 b are zones with         which the user applies the cosmetic product on the lips and/ or         the skin.

Advantageously, the sleeve 14 and the first application zone 20 a are is integral or carried out with a continuity of material. The term “continuity of material” means that the first application zone 20 a is in the extension of the sleeve 14, i.e., the first application zone 20 a is linked to the sleeve 14. The term “continuity of material” also means that the application zones, the means of articulation and the sleeve are designed in such a way as to form a single part, of a single piece, without assembly of the subassemblies together.

The application portion is linked to the sleeve 14 by the intermediary of the first application zone 20 a. Advantageously, the transversal section is substantially constant between the rod 40 and the first application zone 20 a. The second application zone 20 b is then linked to the first application zone 20 a by the intermediary of the means of articulation 20 c. Alternatively, the rod 40 and the sleeve 14 are carried out with a continuity of material. In other words the rod 40 and the sleeve 14 are a single part. The application portion 20 can also be glued, overmoulded, clipped, inserted, embedded at the end of an assembly formed by the rod and the sleeve 14.

The means of articulation 20 c allows for a rocking movement of the second application zone 20 b with respect to the first application zone 20 a on either side of a plane of symmetry of the applicator tip, the plane of symmetry being defined by two axes X, Y of an orthonormed coordinate system X, Y, Z of which the direction X is confounded with the main direction. The rocking movement is carried out around a direction of which at least one of the components is confounded with the axis X.

The means of articulation 20 c separates the first and second application zones 20 a, 20 b by forming at least one reservoir 23 of cosmetic product between them. When the sleeve 14 is assembled to the rod 40, the portion in the vicinity of the proximal end 13 of the application portion, then confounded with the vicinity of the hollow distal end of the manipulation rod 40, is a portion 15 on which the cosmetic product is not or is hardly embedded after an immersion of the applicator tip 10 in the receptacle 50 of cosmetic product, while the reservoir 23 is a portion in which the cosmetic product is embedded in a larger quantity after an immersion. In other words, the reservoir 23 has the advantage of being used as an intermediate reservoir for the cosmetic product to be applied, which provides assurance to the user of having enough cosmetic product on the applicator tip 10 in order to apply make-up, in a single application without having to reload the applicator tip 10 with cosmetic product.

Moreover, the reservoir 23 creates a space between the first and second application zones 20 a, 20 b, and as such participates in favouring the tilting of the second application zone 20 b with respect to the first application zone 20 a. Indeed, the reservoir 23 (or space) allows for a degree freedom for the tilting of the second application zone 20 b. In other words, the second application zone can tilt with a larger amplitude, substantially corresponding to the width e23, measured along the axis Y of the orthonormed coordinate system X, Y, Z, of the space between the first and second application zones 20 a, 20 b, before the edge thereof strikes the first application zone 20 a (FIGS. 3 and 6). The width e23 is of about a millimetre, preferably between 0.5 to 5 mm, more preferably of 1.5 mm.

Preferably, the orthogonal projection of the reservoir 23 in the plane of symmetry X, Y has a curved shape generated by a parametric curve in the plane of symmetry X, Y. Preferably, the curved shape follows the curvature of the application portion 20, in particular the inner curvature of the first application zone 20 a (FIGS. 1 and 4) and its width e23 will be in particular identical from the distal end 16 to the proximal end 13 of the application portion 20.

Alternatively, the shape of the reservoir in orthogonal projection of the reservoir 23 in the plane of symmetry X, Y can vary. Indeed, the width e23 can vary along the main direction. In other words, the reservoir 23 (or the space) can have a width e23 that is smaller at the distal end 16 of the application portion 20 and larger at the proximal end 13 of the application portion 20, and vice versa. Alternatively, the width e23 can also be smaller at the distal 16 and proximal 13 ends of the application portion 20 and larger at the centre of the application portion along the main direction.

In a first embodiment shown in FIGS. 1 to 3, the means of articulation 20 c is a strip of material of which the thickness e20 c measured along the axis Z of the orthonormed coordinate system X, Y, Z is of about a millimetre, preferably between 0.3 and 1 mm, more preferably of 0.5 mm.

In this first example, the application portion includes two reservoirs 23 located on either side of the means of articulation 20 c. In other words the means of articulation is used as a partition between the two reservoirs 23. The presence of two reservoirs makes it possible to accumulate more cosmetic product and a more uniform restitution on the portions to which makeup is to be applied. Here, the shape of the two reservoirs is identical. Alternatively, the shape of the two reservoirs can be different.

In a second embodiment shown in FIGS. 4 to 6, the means of articulation 20 c is presented as a plurality of bridges of material 24 connecting the first and second application zones 20 a, 20 b in a finite number of points. The application portion 20 has as such, between the first and second application zones 20 a, 20 b, a hole 21 allowing the user to see through the application portion 20 (FIG. 4). In this example, the application portion 20 includes a single reservoir 23 distributed on either side of the bridges of material of the means of articulation 20 c. In other words, the hole 21 makes it possible to have a single reservoir with a more substantial storage volume of cosmetic product. This also makes it possible to prevent the cosmetic product from stagnating and as such improves the restitution thereof, as the cosmetic product can pass through the hole 21.

In addition, the hole 21 provides flexibility in the direction of the axis Y. The term “flexible” means deformable in particular at a pressure exerted by a user, in particular when touching the portion to which makeup is to be applied, such as the lips of a user. In other words, when a pressure is exerted on the second application zone 20 b, the latter can tip or be “crushed”. The term “crushed” means that the second application zone 20 b, under the pressure exerted by a user or by the wiper, strikes the inner curvature of the first application zone 20 a. In other words, the second application zone 20 b under the pressure exerted by a user, reduces the hole or the volume of the reservoir. This flexibility makes it possible, on the one hand, to restore the cosmetic product stored in the reservoir 23, to allow for an easier passage thereof on the wiper, but also to increase the facility with which the second application zone 20 b can tip compared to the first embodiment including the strip of material.

The applicator tip 10 can advantageously be obtained via injection. In particular, the sleeve 14, the first application zone 20 a, the second application zone 20 b and the means of articulation 20 c are moulded together, preferably in a single material. Advantageously, these are thermoplastic elastomers (TPE), butadiene-acrylonitrile copolymers (NBR), silicones.

It can however be imaged that the applicator tip be obtained via bi-injection, assembly or overmoulding. The rod 40, the sleeve 14, the first application zone 20 a, the second application zone 20 b and the means of articulation 20 c of the applicator tip 10 can then be made of different materials.

A flexible and soft material can as such be chosen for the application zones 20 a and 20 b, an elastic material for the means of articulation 20 c and a more resistant material for the rod 40 and the sleeve 14. The different materials must be compatible in order to provide a durable and resistant fastening between them. The rod 40 and/or the sleeve 14 can for example include a thermoplastic material such as polypropylene (PP), polyethylene terephthalate (PET) or poly-oxo-methylene (POM). The application zones 20 a, 20 b are more preferably made of TPE and the means of articulation 20 c is made of TPE.

Alternatively, the rod 40 and the sleeve 14 are carried out with a continuity of material. In other words the rod 40 and the sleeve 14 are a single part.

Alternatively the rod 40, the sleeve 14 and the first application zone 20 a are carried out with a continuity of material. In other words the rod 40, the sleeve 14 and the first application zone 20 a are a single part.

FIGS. 7 and 8 show an applicator assembly for a cosmetic product, including a receptacle 50 including a body 51 forming a reservoir intended to contain the cosmetic product, and an applicator including a tip 10 such as the one of the first embodiment described hereinabove. The applicator is adapted to be fixed onto the receptacle 50, in such a way that the applicator tip 10 is housed inside the reservoir. It is as such immersed into the cosmetic product marked 80 in FIG. 7.

FIG. 7 also shows the sleeve 14 assembled with a rod of the applicator, referred to as manipulation rod 40.

The rod 40 allows, among other things, a manipulation of the applicator tip 10. More precisely, the applicator includes a closing cap 70 adapted to be manipulated by the user and the rod 40 extends advantageously from the cap 70.

Note here that the cap 70 is formed of a head 71 from the material with the rod 40, and of a cover 72 mounted by force and maintained in position on the head 71 of the rod 40 using internal counter-forms intended to cooperate with forms created on the head 71. The cover 72 is rigid. The term “rigid” means not deformable either at atmospheric pressure not at a pressure exerted by the fingers of a user. It is with the assistance of the cover 72 that the user manipulates the applicator of the invention, in particular because the cover 72 imparts the movement that the user gives to it to the head 71 of the rod 40, which itself transmits this movement to the sleeve 14 with which it is assembled.

The cap 70 is intended to be fixed in a removable manner to an opening belonging to the receptacle 50 (see FIG. 7 pour the assembled version and FIG. 8 for the exploded version). The opening is here a neck 52 through which the cosmetic product can be extracted.

Note that the sleeve 14 and the rod 40 each have a substantially cylindrical shape and a longitudinal extension main direction confounded with the main direction X.

Alternatively, the sleeve 14 and the rod 40 can each have a polygonal shape.

Also note that the assembly between the sleeve 14 and the rod 40 is an embedding. Alternatively, the applicator tip can be overmoulded on or through the rod.

FIG. 8 is an exploded view of the applicator assembly of FIG. 7. FIG. 8 shows the receptacle 50 in detail. In particular, the receptacle 50 includes a wiper 60, intended to be fixed inside the neck 52.

It can also be seen, in FIG. 8, that the wiper 60 includes a wiping orifice 61 configured to scrape the excess cosmetic product on the rod 40 and on the applicator tip 10 when the latter pass through it.

The wiping orifice 61 is advantageously of cylindrical shape; this choice is not limiting and any other shape of the orifice 61 can be chosen for the wiper 60 without leaving the scope of the invention.

The diameter d61 of the wiping orifice will advantageously be chosen in relation with the diameter D of the rod 40 and the small diameter d of the applicator tip 10 of which it scrapes the excess product embedded.

In this regard, note that the diameter D of the rod is comparable to the diameter d of the application portion 20. Indeed, the application portion 20 here has a section transversal to the main direction X marked within a circle with a variable diameter along the axis X and of which the maximum diameter is d, the two diameters D, d are advantageously linked by the following formula: 0.9≤d/D ≤1.5.

As such, by way of example, the diameter D of the rod 40 can be equal to 6.3 mm and the diameter d of the application portion 20, to 7.5 mm. This furthermore means that the diameter D of the rod will substantially be the same, even substantially less than that of the application portion 20.

Also note that the diameter d61 of the wiping orifice 61 is substantially the same as that of the rod. This has the advantage of scraping the product on the applicator tip 10, and in particular of scraping the product on the application portion 20 of the applicator tip 10. In addition, the presence of the reservoir 23 has the advantage of limiting the force required for the extraction of the applicator from the receptacle and more particularly the force required to extract the application portion 20 from the wiping orifice 61, since the reservoir 23 allows for a certain deformation of the application portion which would not be possible if the latter were full.

As such, in addition to having a large application surface, the applicator assembly is designed in such a way that the wiping of the application portion 20 is optimised when it is extracted outside of the receptacle 50. In other words, the cosmetic product that the application portion 20 is able to embed is scraped in an optimised manner by the wiper 60 through which it passes when it is extracted from the receptacle 50.

This participates in providing the applicator tip 10 of the invention with a capacity to apply make-up to the two lips of a user, and this with the first passage of the applicator tip thereon.

Indeed, the invention advantageously relates to a the applicator assembly of which the receptacle 50 is filled with cosmetic product, with the product being in particular intended for applying make-up to the lips of a user.

The application portion 20, and more particularly, the application zones 20 a and 20 b can be smooth. Note that, as a non-excluded alternative of the invention, they can also have a flocking on their surface, with the flocking including in particular cotton or nylon. Flocking allows for better retention of cosmetic product and a softer touch. The diameter of the application portion 20 provided with flocking is larger by 0.3 to 2.6 mm, for example, according to the flocking chosen.

According to other alternatives, the application zones 20 a, 20 b can carry a material on their surface or include grooves, in particular of shallow depth, in particular from 200 to 300 micrometres. The material provides a surface condition of which the roughness is modified with respect to that of the application zones 20 a, 20 b taken bare.

By way of example, the applicator tip 10 will have a height h10 of about 22 mm (see FIG. 8) measured between the distal end 16 of the application portion 20 and a proximal end 18 of the sleeve 14, along the main direction X.

Once assembled to the rod, the sleeve 14 of the applicator tip 10 is no longer visible, as it is embedded in the rod 40, in particular at the free end of the latter. The visible applicator tip 10 is then the application portion 20. By way of example encore, the height h′10 of the visible portion, measured along the main direction X, is about 12.5 mm.

A narrowing over the entire length of the application portion, even an absence of material at certain points, makes it possible to define at least two application zones at the applicator tip and to render mobile one of the zones in relation to the other by forming a means of articulation. This narrowing confers a particular shape to the applicator tip which as such has a limited rigidity. A more flexible tip is as such obtained which adapts to different users and to their methods of applying make-up with comfort in use.

In addition, this narrowing makes it possible to form at least one reservoir allowing for the storage of cosmetic product. The user can as such apply cosmetic product on a more extended surface of a single piece before having to immerse the tip again in the receptacle.

In order to obtain additional advantageous effects, the embodiments can be combined without leaving the scope of the invention.
